A new specimen of Heterodontosaurus elucidates how ornithischian dinosaurs evolved a body plan substantially different from that of other dinosaurs and what these differences meant for their breathing.

Genetic barriers to gene flow maintain divergent linked substitution rates in hybridization.

Fruit consumption of Jeholornis was evidenced and indicates seed dispersal was present from early in avian radiation.

Understanding novel cell types and their evolutionary history is re-evaluated using single nuclei transcriptomic approaches and their inferred underlying gene regulatory networks.

Host characteristics drive the assembly of similar communities within the convergently evolved and geographically distant pitcher ecosystems of carnivorous pitcher plants.

Molecular structure of mitochondrial complex I from Drosophila melanogaster reveals a structural element not seen in other organisms to date that may regulate the transition between an off-pathway resting state and the active state of the complex.

Open questions of cancer adaptive therapy are discussed through the lens of mathematical modeling, categorized into three sections, (1) integrating appropriate components into mathematical models, (2) dosing protocol design and validation, and (3) challenges and opportunities in clinical translation.

A lexicon to help scientists and philosophers discuss the meaning of function in molecular biology more clearly is proposed.

Shared traits in gaze patterns and brain activations between marmosets and humans during Theory of Mind animations reveal cross-species cognitive similarities.

Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.
